SEAPEX, Kuala Lumpur, Malaysia
Kuala Lumpur (pop. 7.2 million) is the capital of Malaysia, and home to the iconic Petronas twin towers, the tallest in the world. The architecture of Kuala Lumpur (or “KL”) is a blend of old colonial influences, Asian traditions, Malay Islamic inspirations, modern, and postmodern architecture mix. Due to its geographical location, KL is a regional centre for many major geophysical service companies. The largest oil company is Petronas (short for Petroliam Nasional Berhad), the national oil and gas company ranked 8th most profitable company in the world by Fortune, and having business interests in 31 countries. Many other oil companies are also represented in Malaysia; large and small. My host on 9 September was the KL chapter of SEAPEX (“KLEX”), and thanks to Chris Howells, the organisation was brilliant. About 140–150 people gathered at a KL Convention Centre (KLCC) meeting room for a lively night of socialization, interrupted for a while by my lecture. I would like to thank Aziz Muhamad for allowing me to also speak to the Petronas Acquisition, Geomatics and Processing Community of Practice (AGP CoP) at the Petronas twin towers earlier on the same day. Thanks also to Jesmee Zainal Rashid (Country Manager, PGS) for facilitating many aspects of my enjoyable trip.

SEAPEX, Manila, Philippines
As summarized, Manila is the capital of the Philippines, and with almost 20 million people, has the 5th largest urban population in the world. Five centuries of successive rule by Spanish, English, American, Japanese, and Filipino regimes have created a uniquely eclectic city, with the most obvious influence being Spanish. Indeed the local unit of currency is the peso, and much of the signage and architecture is Spanish in influence. The highly decorated jeepneys are an iconic mode of transport in the most densely-populated city centre in the world.
I was, however, located in the business district of Makati City, which lacked the color and vibrancy of downtown Manila. My society host this time was SEAPEX (South East Asia Petroleum Exploration Society), the main regional oil and gas professional organization, based in Singapore. A thanks goes to Chris Jackson (Pitkin Petroleum) and Marian Glorioso (Supply Oilfield Services) for helping to organize my lecture at the Philippines SEAPEX event. In contrast to some other regional locations that host monthly SEAPEX meetings, Manila only host about four each year. Located at La Souffle restaurant, on top of the Citibank Building, the evening hosted 70 people. In characteristic style, the technical presentation was preceded and followed by drinks, and a buffet meal was served afterwards as well. Sponsors for the night were PGS.
Most reservoirs in the Philippines are carbonates, and the overburden and near-surface in offshore areas are often affected by carbonates too, presenting challenges to seismic imaging. So, again, the topic of my lecture was relevant. After three long days of travel, I now take a six week break before my next lecture in Kuala Lumpur, Malaysia.

ASEG SA/University of Adelaide, Adelaide, Australia
The final destination in the clockwise circumnavigation of Australia, before the flight home to Perth the next morning was Adelaide. Adelaide (pop. 1.1 million) is the capital of South Australia (SA), and is known as the “city of churches”. Located on the Torrens River, Adelaide is a picturesque city of parks, classic architecture, and naturally, many churches. The main oil company is Santos, active in SE Asia, the largest onshore operator and also about to become another major CSG player. SA is also home to a growing geothermal industry, and one of only two Australian states actively mining uranium.
My evening lecture attendee quality was extremely high and the event was most enjoyable, probably assisted by the catering and wine for which SA is also famous. Luke Gardiner of Beach Petroleum deserves special mention for actively promoting and organizing the event. On a final note, I observe that Beach Petroleum are probably indicative of the future direction for oil companies, being active in conventional hydrocarbon exploration, CSG and geothermal. Coupled with oil shale production and carbon capture and storage (CCS), the future of seismic geophysics in Australia has enormous opportunities; but currently needs significant revitalization to meet these challenges.
I also thank Michael Asten (ASEG Federal President), Ray Boyd, Cathy Higgs, Chris Nicholson, Kerrie Deller, Kevin Lanigan, and Koya Suto for their efforts and time to help make my Australian tour rewarding and interesting. I hope the bridges built develop into future cooperation.
14 July 2009
ASEG VIC/PESA, Melbourne, Australia
Another early-morning flight, followed by a scramble to arrive in time at the lunch session hosted by the Victorian branch of PESA at the Victoria Hotel, and chaired by Gordon Wakelin-Jones (NAME). Melbourne (pop. 3.9 million) is the capital of Victoria. Known for often experiencing four seasons of weather in a day, Melbourne is exposed to weather patterns originating in Antarctica, and has been derisively referred to as “bleak city” by other more sunny capital cities in Australia. Significant investments by successive state governments in the last two decades, however, have developed Melbourne into the cultural and sporting capital of Australia, a thriving metropolis that has wonderfully capitalized upon the innumerable city laneways and alleys to build a café, restaurant and shopping paradise. Located on the Yarra River, Melbourne enjoys an incredible public transport system of trams and trains.
Australia’s original major oil discoveries were in the nearby Gippsland Basin, where ExxonMobil (Esso Australia) continues to be the major operator. Although much attention shifted in the 1980s to the gas-prone North West Shelf, several smaller oil companies continue to explore in the Gippsland, Bass and Otway Basins. The Otway Basin remains the most frustrating and unrealized basin, for despite outstanding source rock quality and well-documented oil slicks, no major discovery has ever been made.
My lunchtime event was held in the Victoria Hotel, a heritage building in the city centre. The 29 people in attendance provided a typically lively feedback.
13 July 2009
ASEG Tasmania/Tasmania University/GSA Tasmania, Hobart, Australia
Hobart (pop. 200 000) is the capital of the island state of Tasmania, located near the southernmost tip of the island, and in the estuary of the Derwent River. Tasmania was originally known as Van Diemen’s Land, and was the first official penal colony for British convicts, begun in 1803. Tasmania ceased to be a penal colony in 1853. The final convict ship arrived in Western Australia in 1868. Now, Tasmania is known for its rugged and mountainous beauty, and its outstanding crafts, food and wine produce. Indeed, my weekend in Hobart involved much pleasure eating and drinking.
Michael Roach was my host, and runs the geophysics program with Anya Reading at the University of Tasmania (UTAS). UTAS have a proud list of alumni, including Sam Carey of expanding earth fame. 28 students and faculty attended my lunchtime lecture, after which we ate at the Faculty Club. Tasmania was another of my tour highlights, and I strongly encourage anyone to visit. My impression is that the three strongest geophysics schools by numbers of students for undergraduates in Australia are Curtin University (Perth), Monash University (Melbourne) and UTAS (Hobart). But, for a country of such incredible mineral wealth, this situation desperately needs to improve.
10 July 2009
University of Ballarat, Ballarat, Australia
Ballarat (pop. 90 000 and the largest inland Australian city after Canberra) was the curiosity in my itinerary. A country town in the southern state of Victoria, Ballarat was a key gold mining centre in the gold rush of the early-1850s. Ballarat was the location of the Eureka Stockade on 3 December 1854, where 22 miners and 6 colonial forces were killed in a confrontation over excessive fees on mining licenses. That day is sometimes controversially referred to as “the birth of democracy” in Australia. But, to return to present day, my host was the University of Ballarat, who has a healthy geology department running under the School of Science & Engineering, and headed by Kim Dowling.
Unfortunately, all the students were on a field trip in the Sterling Ranges, South Australia (it was semester break), so only 6 university and local professional people were in attendance at my late-afternoon lecture. As Ballarat is close to my birthplace of Bendigo (another gold mining town), 8 family and friends improved the numbers to more respectable 14. The two consolations were that the students can eventually watch the SEG web cast of my lecture, managed by Kim Dowling, and that a bridge now exists between the SEG, myself, and the University of Ballarat.
9 July 2009
ASEG ACT, Canberra, Australia
Canberra (pop. 350 000) is the capital city of Australia, located in the Australian Capital Territory (ACT) because the forefathers of Australia could not agree whether Sydney or Melbourne should become the national capital. Federation began on 1 January 1901, more than 120 years after the First Fleet of settlers arrived in Botany Bay. The site of Canberra was selected in 1908 following an international contest for the design, awarded to Chicago architects Walter Burley Griffin and Marion Mahony Griffin. Construction commenced in 1913.
Australia’s main government geosciences body is Geoscience Australia (GA), who were my host for a lunch ASEG event. GA look at key issues such as the global attractiveness of Australia's offshore and onshore exploration, improved resource management and environmental protection. The outcome of their work is an enhanced potential for the Australian community to obtain economic, social and environmental benefits through the application of first class research and information. An early morning flight from Sydney arrived too early for check in, so it was straight to business at GA. Special thanks go to Bruce Goleby and Ron Hackney for devoting an entire day sharing the activities of various groups and departments, all working in a spectacular building well worth visiting – as is their web site.
An audience of about 40 again provided lively feedback, and then the promised “fantastic” lunch was duly delivered. Canberra was definitely one of the highlights on my fleeting tour.
8 July 2009
PESA/ASEG NSW, Sydney, Australia
This time the meeting was hosted by the New South Wales (NSW) branch of PESA as an evening event, held in the Rugby Club, and chaired by Phillip Cooney. Sydney (pop. 4.4 million) is the capital of NSW, and is built around Port Jackson, which includes Sydney Harbour. Home to the iconic Harbour Bridge and Opera House, Sydney was the first city developed in Australia after the First Fleet of settlers arrived at nearby Botany Bay on 26 January 1788.
NSW also remains largely unexplored offshore, although the offshore Sydney Basin is believed to be prospective. An audience of 20 provided a warm welcome in very rustic settings, and question time was again quite lively. The 2010 meeting of the Australian SEG (ASEG) will be held in Sydney. Particular thanks to Mark Lackie (Macquarie University) for helping to organize the event. Mark produces a handful of geophysics graduates each year, as do the University of NSW.
7 July 2009
ASEG QLD, Brisbane, Australia
After flying into Brisbane from Perth on Monday, the first of seven lectures in different Australian cities on seven consecutive business days commenced. Hosted by the Queensland (QLD) branch of PESA (Petroleum Exploration Society of Australia), an excellent lunch was provided by the Chifley on Lennons Hotel, and chaired by Sue Slater. Brisbane (pop. 2 million) is the capital of QLD, and is located on the Brisbane River. Revitalized after hosting the World Expo in 1988, Brisbane has been the fasting-growing capital city in Australia for many years, thanks in large part to the warmer climate and attractive lifestyle.
By far the largest oil company of note in QLD is Origin Energy, who have been one several large players making movements into coal seam gas (CSG) developments in Australia. Onshore CSG is believed to host more gas than the North West Shelf, and several major trains are in planning. Unfortunately, geophysics plays a negligible role in the discovery, characterization and production of CSG, as the overwhelming strategy simply involves drilling many holes. The properties of pressure and permeability, however, are critical in terms of production, so an opportunity still exists for seismic to play a role in the future of CSG. Offshore, most of QLD is protected waters, home to the Great Barrier Reef, and remains unexplored.
In the meantime, my lunchtime lecture was of relevance to offshore, conventional hydrocarbon exploration. A recurring theme of Q&A time has been the merits of “legacy MAZ” processing (using overlapping 3D surveys in processing to upgrade the existing data value), and this was again a strong topic of discussion amongst the 31 people in attendance. Particular thanks to Wayne Mogg for helping to organize the event.
Attendees chat before the lecture begins in Perth.

PESA-ASEG, Perth, Australia
The Petroleum Exploration Society of Australia (PESA) and the Australian SEG (ASEG) were joint hosts to my lecture in Perth. Both societies host monthly meetings in most Australian capital cities, with PESA generally being larger, particularly in Perth, the home to Australia’s oil and gas industry. A large luncheon crowd of 188 had the nerves tingling, and the pressure was on, particularly as PESA lunches are usually exploration or geological case studies, rather than hardcore seismic technology presentations. Kerrie Deller (PESA) and Cathy Higgs (ASEG) deserve special mention for gathering so many people. Clearly, the lecture theme is a topical one! The lecture was videotaped for the SEG web site, and I was feeling the nerves under the glare of the halogen lights. Nevertheless, it seemed to go well, and the audience was exceptionally attentive, asking a series of probing questions at the end.
Perth is the most isolated Australian capital city, perched on the western coast, at least three hours flight time from the nearest Australian capital city. Home to about 1.3 million people, Perth is nevertheless the gateway to Asia and the North West Shelf (NWS), host to most of Australia’s hydrocarbon exploration and production activity. Australia produces 9% of world LNG, most of it from the NWS, although coal bed methane (CBM) from the onshore eastern regions of Australia are rapidly growing in scale and significance. Much of the NWS is challenging for seismic exploration, primarily because of complex seismic multiples and noise types associated with extensive carbonates in the near-surface. The NWS Joint Venture (NWSJV) is a consortium of six major companies, and have recently completed the first multi-azimuth (MAZ) seismic project. Initial (unpublished) results demonstrate significant improvements in signal-to-noise content, and thus the issue of “azimuth” will have greater prominence in the near future.
Special credit goes to the table that formed a pact to sip their wine each time I uttered the word “azimuth”! The waiters would have been busy serving that table.
Early morning in Melbourne city, looking north to Flinders Street Train Station across the Yarra River.

University of Melbourne, Melbourne, Australia
A drive across Melbourne (population 4 million) with Michael Asten followed, with time to set up and speak to the Melbourne chapter of the Australian SEG (ASEG) in the evening at the University of Melbourne. My hosts were Michael Asten (ASEG Federal President), Asbjorn Christensen (ASEG State President), and Gordon Wakelin-King (PESA State President). There seems to have been some confusion with the lecture announcement, as a small group of 12 were in attendance. No loss though, as I return on 14 July to speak to the state PESA chapter in Melbourne. The group who did attend was well informed and animated, and discussion was rewarding and interesting. A long day concluded with an outstanding dinner with my hosts in the Southbank Complex on the banks of the Yarra River.
The University of Melbourne has about 44 000 students, and is located on the northern edge of the city. Melbourne is the cultural and sporting centre of Australia, although that point may be disputed by some in Sydney! Well-known for routinely hosting all four seasons of weather each day, this day was no exception, with the city slowly emerging from a brisk cover of dense fog in the morning, to eventually be replaced by sunshine and a light rain. The past decade or so of state governments have invested heavily in the city and surrounds, and it seems that virtually every laneway contains a myriad of cafes, restaurants, and coffee shops, and Melbourne is a shopping and artisan mecca. I have fond memories of moving from my country home to the bustle and energy of Melbourne as a naïve teenager. These days the School of Earth Sciences unfortunately no longer has a Geophysics group, following the retirement of long-serving legend Lindsay Thomas. I hope the university can still nevertheless find a role in our future energy industry.
Speaking inside the AuScope Laboratory
21 May 2009
Monash University, Melbourne, Australia
Monash University is Australia’s largest university with about 55 000 students, and eight campuses; six in the state of Victoria, and one in each of Malaysia and South Africa. The School of Geosciences is very strong, with 270 current first year students. That number drops off to about 75 by third year, but there are 30 four year Honours students, 5 M.Sc., and 33 Ph.D. students. Research in the School is funded from national competitive grants and collaborative research grants from industry and government organizations. The School is part of the national Co-operative Research Centre for Predictive Mineral Discovery and the national AuScope crustal imaging and modeling networks, both Australian government research programs. My hosts were Michael Asten and Ray Cas.
The Clayton campus is quite vast, and is evidently undergoing several new building developments. After lunch in an excellent university café, I spoke to about 30 people in the impressive AuScope Laboratory, notable for the large projection screens lining all four walls, so that the audience could look in any direction and see my presentation! Discussion went on afterwards with several third year and graduate students, relocating to a smaller venue upstairs. Despite having received my first degree at the University of Melbourne, I had never been to the Monash campus before. Nevertheless, I was impressed with what I saw, and look forward to closer and productive ties in the future.
University of Otago campus
19 May 2009
University of Otago, Dunedin, New Zealand
The University of Otago, founded in 1869, is New Zealand's oldest university, and has more than 20 000 full-time students. The university is ranked number one for research by the New Zealand Government’s formal tertiary institution research performance assessment. The Department of Geology has 9.5 full time teach positions, about 30 M.Sc. and Ph.D. students, and an annual first year intake of 120–200 students. A small but enthusiastic geophysics group is led by Andrew Gorman, pursuing a variety of controlled source seismic research projects. Unfortunately, Andrew was on sabbatical leave during my visit, but doctorate student Claudine Curran and Michael Palin were gracious hosts.
Set in the far southwest of New Zealand, Dunedin was settled in 1848, and stands on the hills and valleys surrounding the head of Otago Harbour. The harbour and hills are the remnants of an extinct volcano. Rich in heritage and culture, the architecture has grandeur reminiscent of Dunedin’s Scottish roots. The university occupies much of the compact town area, which has a population of about 120 000. An early morning flight on a smallish propeller plane arrived in glorious sunshine, although the light snow cover on the mountains to the west alluded to the cold air outside. Well known as a graveyard for visiting international rugby union teams, Dunedin gave a taste of its better known climate by lashing us with rain as we waited on the tarmac for the evening flight back to Wellington.
The great variety of international students I met were testament to the merits of Dunedin as a place to experience the pristine beauty of New Zealand, and to receive a top quality education. After a hearty lunch in the cost Faculty Club, a group of about 20 listened attentively to my lecture, and then there was barely time to visit the university museum with Claudine, where an exhibition of photographs from Antarctica showed the stark reality of that barren continent. Then back to the airport as the night and weather closed in, and a tiring but memorable day.
Panorama of Wellington harbour
18 May 2009
AAPG Chapter, Wellington, New Zealand
Wellington, New Zealand's capital city of 180 000 people is set on the edge of a stunning harbour and surrounded by rolling (i.e. steep) hills. Known to locals as “Windy Wellington,” my host was the local AAPG chapter, with the lecture coordinated by John Pfahlert, Executive Officer for the Petroleum Exploration and Production Association. After about 12 hours of overnight flight connections from Perth, I arrived to a sunny but cold Sunday, and explored the picturesque harbour. New Zealand is a truly beautiful and pristine country, a geologist’s paradise, set between two subduction zones, with soaring snow-capped mountains, glaciers, sweeping green valleys, active volcanoes, and seemingly unending vistas. The people of layback and welcoming, and I cannot recommend New Zealand enough as a most affordable paradise for outdoor lovers and gastronomes keen to sample the equally spectacular food and wine produce. Indeed, the first evening hosted a memorable dinner of local seafood and wines.
After a day with the Crown Minerals, who manage the New Zealand Government's oil, gas, minerals, and coal resources, known as the Crown Mineral Estate, at was time to give the lecture. Sixteen people from the AAPG Wellington Geoscientists chapter attended the lecture at the Kensington Swan Law Offices, which affords a scenic view over the harbour. New Zealand poses significant challenges to offshore seismic surveys, primarily because of consistently poor sea states, and the country remains grossly unexplored. This latter fact is compounded by New Zealand’s geographical isolation. The Maui gas field in the Taranake Basin to the west of New Zealand contains about three-quarters of the country’s hydrocarbons, and dominates energy supply. Significant new reserves are obviously required going forward to support economic stability. The small but enthusiastic audience was receptive to innovations in seismic technology, particularly those applicable to producing better images in complex geological environments, capable of environmenting in demanding conditions.

Institute of Technology, Bandung, Indonesia
The Institut Teknologi Bandung (ITB) is located 180 km east of Jakarta in the hillside town of Bandung, which has a population of about 2 million. Set in mountainous terrain, Bandung is home to many shopping factory outlets, seemingly endless food stalls, restaurants and discos, and the chaotic colors and smiling faces of Indonesia. We drove in mid-afternoon on a Friday to escape the weekly migration from the heat and bustle of Jakarta to the cooler quiet of Bandung that traditionally occurs later in the day. Indeed, a large percentage of workers in Jakarta come from Bandung. The student population of ITB is about 15 000. The Geophysical Engineering Study Program at ITB was founded in 1989 as part of the Faculty of Mining and Petroleum Engineering, and is the largest university geophysical program in Indonesia. The department has 25 lecturers and 9 staff, with an annual intake of 75 new students, most of whom complete the undergraduate course. Overall, there are about 200 students in the department. ITB resembles a traditional university campus in western countries, with the addition (on a Saturday at least) of an eclectic collection of food stalls, horse and buggy rides, and various cultural attractions.
The student body of the department is named “TERRA”, and has 200 active members and 19 officers. The current president is Pratama Abimanyu. The student body has declared itself as a professional organization, and as such, must provide a strong technical program of workshops, field trips, seminars and guest lectures, and company visits for its members. TERRA will conduct the Indonesian Geophysics Students Scientific Meeting (IGSSM) in November 2009 to commemorate two decades of Geophysical Engineering Study Program in ITB. Representatives from all geophysics faculties around Indonesia will profile the latest advancements in geophysics, and the IGSSM will serve as a national seminar, geophysics exposition and focus discussion.
Permadi Satrio, Astrida Listyadewanti, Andrew Long, Christine Kaharmen, Sheila Anastasia, and Reza Pasha
My host was the ITB Geophysical Society, the SEG Student Chapter of ITB. The current President is Reza Pasha Amarullah Bekti, who has overseen the reactivation of the chapter after a two year hiatus, including a threefold increase in SEG student membership. Despite it being a Saturday morning (again), my “extended” lecture was attended by 103 students and faculty, and I am particularly grateful for the efforts of Reza, Christine Kaharmen, Rachmat Sule, and Darharta Dahrin for organizing such a well attended event. Question time was treated earnestly and energetically, and again I was impressed with the students, many of whom I hope to maintain contact with in future. I also thank Suprapto (Senior Advisor, PGS) for his selfless time and efforts to make everything in Indonesia a success.
A few industry people also made the drive up from Jakarta to attend the lecture. I will return to Jakarta on October 8 to give the lecture again to the Indonesian Petroleum Association (IPA).

Gadjah Mada University Geophysical Society, Yogyakarta, Indonesia
The most obvious landmark when flying into Adisucipto International Airport is the Mount Merapi volcano (Gunung Merapi: Mountain of Fire), Indonesia’s most active volcano. Yogyakarta is otherwise fairly flat, characterized by an eclectic collection of small shop fronts, lush green rice and agricultural areas, and the sprawling Gadjah Mada University area.
From the moment I left the airport into the warm, clean air, the welcome by the students and faculty alike was quite overwhelming. The Indonesian people were incredibly gracious and friendly wherever we went, and I recommend Indonesia as a destination to visit for business or pleasure. My most vivid memory is the food: So much of it, and all so good. Served by fresh water reserves from nearby highlands, Yogyakarta has clean air and and is served by abundant fish stocks in nearby seas. The cuisine varies quite significantly in different regions of Java, as I discovered, and immense thanks to our hosts for their hospitality!
Faculty and organizing committee. From left: Goldy, Agus, Gama, Wiwit Suryanto, Rernat, Kirbani Sri Brotopuspito, Andrew Long, Haryo Wahyu, Mochamad Nukman, Sismanto, Suprapto (Senior Advisor, PGS), and Ikhsan
The Geophysics Study Program at Gadjah Mada University is based within the Faculty of Mathematics and Natural Sciences. Accredited Level A (best) by the National Board of Accreditation (ISO 9001:2000), there are currently 222 students (undergraduate and graduate). The lecturers include 16 geophysicists, 17 scientists, and 6 supporting staff. My main hosts were H. Kirbani Sri Brotopusito and Haryo Satriyo Wahyu. We managed two excellent dinner and lunch events, along with the lecture itself, so the first leg of my tour was a whirlwind of delicious food and smiling faces.
Although Saturday is not normally a working day, almost 50 students and faculty provided an overwhelming reception. Whilst the lecture topic may be unusual for a student group, everyone listened attentively, and there was plenty of productive questions and discussion afterwards. I thank everyone for their welcome and gifts of two special momentos. One desk plaque is engraved with the words “Global Partner for Better Indonesian and Human Life." Indeed, I do hope that this visit is only the first part of a long partnership with Gadjah Mada University, and I look forward to the students developing successful careers and lives. Geophysics will expose them to a world of opportunities and challenges. Likewise, I invite the world to visit Indonesia and see just how enthusiastic and capable the students there are. Offers to help the faculty with industry donations of geophysical software and future lectures and industry partnerships are welcome, so I hope the SEG lecture is only the first of many such partnerships between Gadjah Mada University and industry.
Yogyakarta is a city in the Yogyakarta Special Region, the island of Java, Indonesia. Renowned as a center of classical Javanese fine art and culture such as batik, ballet, drama, music, poetry, and puppet shows, it is also famous as a center for Indonesian higher education. Indeed, the city nickname is “Kota Pelajar” (Student City). Home to half a million people, Yogyakarta is known as the second most important tourist destination in Indonesia besides Bali. The northern part of the city is home to Gadjah Mada University, the oldest and most prestigious public university in Indonesia.
